table 1 --- master1   table2 --- custinput1

Based on the count of masterid I get from custinput1, I want to know how many posibilities are in master1.  Customer submits input file, which loads table custinput1.  The first query tells me how many records are linked to masterid in  custinput1.  I need to then take the masterid from the custinput1 file and compare how many more records are available in the master1 table.

This query tells me how many records are linked in custinput1:

select count(distinct masterid) from custinput1
  where exampleid = '3323'  and numberoflinked >0

Now I want to see how many are in master1. I'm trying...but it doesn't work., I get 0

select count (numberoflinked) from master1 where masterid in
(select count(distinct masterid) from custinput1
  where exampleid = '3323'  and numberoflinked >0)
